[RPG] nything that can create a fire that burns underwater


Is there any fire-related item or spell in D&D 5e that can create a fire that can burn underwater?

Best Answer

The fifth level evocation Immolation from the Elemental Evil Player's Companion wreathes a creature in flames.

These magical flames can’t be extinguished through nonmagical means.

Since water is non-magical, an Immolated target should burn quite nicely underwater.

(For up to 1 minute, if you concentrate, and they fail their save.)
